Now Mistress Yuliya wants to see how much pain the slave's hands can handle. She handcuffs hi to the radiator so there is no escape from Her heels on his hands. she binds his legs so he can't thrash around to much. She then starts the torment by digging Her heels into his palms. The action gets more and more intense as She increases the level of pain until the slave is in absolute agony as She stands full weight on his palms for long periods.
